rlhis computing machine comprises, generally, recording elements, controlling mechanism for governing the setting of the recording elements, and mechanism for actuating the recording elements an amount determined by the controlling mechanism.

rThe invention includes, generally. recording elements of different denominations, mechanisms for actuating one of said elements, means for controlling the actuation of said element by said mechanism, and mechanism for additionally actuating said element and actuating the other element a proportionate amount, that is, an equal amount. in the terms of the units of the latter clement, ln the illustrated form of my invention, the element of higher denomination iirst actuated an amount determined by the controlling mechanism and 'the element of higher denomination is then additionally actuated and the additional actuation is transmitted proportionally to the element of lower denomination. As the machine illustrated herein is for computing and recording elapsed time, the element of higher denomination registers hours and that of lower order registers fractions of hours and prefsrably decimal fractions; and any fraction or an hour first set in the hour element is transferred in terms of tenths to the fra -tion recording element. Hence, a

one-half hour or one-half of aspace on the hour element is transferred into five spaces to the demical recording element.V v

In this embodiment of my invention, the actuating and controlling mechanisms operate one recording element to set therein the amount to be computed including the fractional amount to be transferred, the mecha'- nism for additionally actuating said element then operates to move said element a fractional amount to bring the even number of unitsV to the recording or printingline and to proportionally advance theother element. In other words, when the amount includes a fraction of a unit of thewheel of higher denomination, or the hour wheel, the

Vadvance of the hour wheel is stopped between two of the printing points'on the Wheel (this point being short of the whole number to be recorded instead of beyond said number, for the reason to beV hereinafter explained) and said element is thereafter additionally advanced to aline the whole number type with the printing line,

and the other element proportionately ad-V vanced to aline the fraction type with the printing line. in this form of my invention, the advance movement of the wheels is in opposite directions. Y Y

1, 2, Figs. 2, 4, andrlfigs. 11 to 18, inclusive, are the recording elements which are shown as wheels loosely mounted on a shaft 3 actuated, as will be hereinafter described, the wheel 1 being a complete wheel and carryling printing characters on its periphery from 0 to 12 inclusive representingl hours; and the wheel 2 being usually a segment loosely mounted on the shaft 3 at the side of the Wheel 1 and having characters on its periphery from O to 9 inclusive, representing decimal fractions of'hours.

This machine is ofthe same character asY that forming the subject-matter of my pending application, Sr. No. 24,672, filed Apr.

4 29, 1915, in which the computing is done not by adding the used units or elapsed time, but by subtractingthe unelapsed time from the total capacity of the recording Wheels. As this machine computes time the capacity of the machine is twelve hours and the Wheels normally stand with thel 12 type of the wheel 1 and the 0 type of the wheel 2 at the printing line; and the advance movement of the Wheel 1 is in ai reverse direction with respect to the order of the type on the hour wheel 1. That is, during the advance of the wheel 1 the numbers pass the printing line in 12, 11, 10, 9, 8, etc., order, instead of Yin O, 1, 2, 3, 4 order. YThe advance of the wheel 2 is in a direction opposite to that of the wheel 1 and the 0 type is normally at the printing line, and the numerals thereof pass the printing line in O, 1, 2, 3 order. Hence if hours elapsed are to be computed, the hour wheel starts from 12, and

the unelapsed time numerals of 12, 11, 10, 9,

pass the printing line with the half-way point of the space between 9-and 8 at the printing line, so that the entire amount of Y 811,- hours elapsed time or hours unelapsed time is set 1n the hour wheel. The wheel 1 is now additionally advanced by the mechanism for'that purpose, to subtract the fraction from the total capacity of 12 hours, or add hour to the unelapsed time of 3?,-

hours making it l hours, so that the numeral hours elapsed time or hours unelapsed time is first set in the hour wheel and Vthen the Wheel 1 additionally actuated to eliminate anyY fraction therein, and the fraction Wheel 2 advanced to receive such fraction, it receiving the fraction in terms of decimals as 5.

The means for actuating the wheels 1, 2 comprises'the shaft 3 and its driving means, and a planetary pinion 4 mounted on a spindle 5 carried at the end of the crank arm 6 mounted on and rotatable with the shaft 3, a rack associated with the wheel 2 as a sun gear 7, and a rack 8 associated vvith'the wheel 1, and here shown'as formed on the inner side of a ring 9 secured on the face of the wheelxl and contiguous With the wheel 2. When the shaft 3 is initially actu ated, the crank arm 6 is rocked toward the rear of themachine, that is, to the right, Figs. 3, 11, 12 and 13, thereby causing the pinion 4 to travel planetarily, so that it tends to actuate the wheel 1 in a rearward direction, that is, in the direction of the arrow Fig. V11. However, the advance movement ofthe wheel of lower denomination, that is, theV wheel 2Y which advance movement is in the reverse direction from the advance movement of wheel 1, is normally yieldingly resisted by suitable means as a spring 10, connected at one end to said wheel and at its lother end to a suitable bracket 11 supported by the main frame 12 '310 From the foregoing, it will. be obvious that the entire amount to be computed as 8:1-Y

of the machine, and the movement of the Y wheel 2 in a retrograde direction is prevented by a fixed stop, or shoulder 13 -on said bracket 11.V Hence, during the initial movement of the shaft 3 and rock arm S, the wheel 2 is held stationary VWhile the pinion el is traveling planetarily about the sun gear 7 and also rotating or acting as a compensating pinion, so that the wheel 1 is advanced bythe rotation of the pinion 4land also by the planetary movement of said pinion 4. The amount of movement of the shaft 3 and parts actuated Vthereby is determined by the controlling means to be described. During this actuation of the wheel l, the even amount to he computed and the fractional amount, is set in said Wheel l.

rlie mechanism for additionally7 actuating the wheel l, and for actuating` the Wheel 2. includes ratchet teeth associated with the Wheel i, and a. paivl lacarried by an actua-tinlg` part as a lever l5 pivoted between its ends at 16 to the bracket l1, said lever having' one arm thereof coacting` with a cani l? mounted on the main shaft 18. and carrying on its other arin the paivl lei which is pivoted at lf) thereto. rllhe pivot-al niovement of the paivl is limited in one direction by aV shoulder 2O on the lever l5 and yieldingl movement of the paivl is permitted dui'- ing the operation of the paivl by a 'spring 2l. rl`he ratchet teeth 22 with which the paivl la coacts are conveniently provided on the periphery of the ring 9 on the vfheel l. rthere is one ratchet tooth for each printing character Q3 on the periphery of the wheel l.

Gbviously, rocking of the shaft 1S over to the right in Figs. il to l5 inclusive, causes the cam l? to rock the lever l5 in such direction as to carry the pavvl le into engagement with the ratchet teeth 22.

rl`he means for transferring the additional movement of the Wheel l effected by the paivl let. to the ivheel Q, preferahl;v includes a part of the means for actuating the Wheel forwardly, as the pinion which, during' the transferring' operation, occupies a. position similar to that shown in l2 and 13. luring the transferring' operation this pinion remains stationary, so. far as its planetary movement is concerned, hut is rotated hy the rack S, 4so that motion is transmitted through said pinion to the sun A`Qjear 1",ivliicli rotates about the shaft 3 to the right Figs. 12 and 13 against the action of the soi-ing` lO and moves the Wheel 2 in its forward direction. The pinion multiplies the retrograde motion of the rack 8. the ratio of ge: 'ing' being such that a single complete movement of the Wheel l by the paivl le actuates the Wheel 2 to the limit of its movement, that is moving the Wheel l one step moves the Wheel 2 a proportionate amount ten of its steps from to 9 inclusive and transfers hours to the Wheel 2. lf, lioivever` the fractional amount set in the ivheel l for instance e hour, the Wheel 2 Will be actuated but half of its movement and the paivl ll lwill slide over one of the ratchet teeth 22. with a lost motion one-half of the length of said tooth. lf. for example, ref rring` to 22. the amount set in the ivlieel l prior to the transferring operation iii Slliours or l2 less 3lliours, then the ivlieel l will be additionally advanced onehrilf one of the spaces of the teet 22 bringingl the numeral 8 to the reading or the printing` line. and the vvlieel 2 will he set ahead i'ive spaces until the numeral 5 comes opposite the numeral 8 so that the record reads lVith other fractions the pa-Wl lli slides over one of the ratchet teeth a greater or less distance. lf, however, as shoivn in Fig. 2l an even amount and no fractional part is set in the hour Wheel as i0 hours, the vpaivl lil Will slide the entire length of a ratchet tooth and no motion Will be transmitted. The ratchet teeth and paivl therefore constitute a varying lost motion connection.

lllhe shaft 18 actuates the shaft 3 as will be presently described, and the cani l? on he shaft i8 is timed to act-nate the lever 5 after the shaft 3 has been actuated, the ever ist normally engaging a lovv concentric vortion 9 on the cam 17 and riding up a lift portion after the shaft 3 has been actuated, then onto a high concentric poi'- tion i7, Figs. ll. l2. and

Although in this embodiment of my iiivention the recording` elements are shoivn as Wheels and the pinion l as a planetary pinion, it .vill be understood that broadly considerech the pinion i is a. traveling and rotating;l pinion meshing' .vith rachis connected to recording elements, and that it is not necessariv in all embodiments of my invention that the pinion e be a planetary pinion or the racl and S be concentric or curved. Further it ivill be noted that the pinion is utilized not only as part of the actiiatinxa` mechanism but also serves to perform function in the operation of transmechanism, so tnat additional mechism for advancing' the ivhecl 2 unessary.

t he means Lor driving' he shaft 3 or for controllingl the driviimY thereof includes the shaft 1S, a segment 230 mounted on the sinn t 3. Figs. 2. 3 and a, pinion 3l meshing' with the segment SO and looseiy mounted on the hearing; QG of shaft 2l. a spring' loca ed in a stationary barrel 33 fixed to the frame. and resisting' nient of the shaft 1S by its handle` a seg'- nient loosely mounted on the shaft iS and iino; with the pinion the hub of which keyed at 36 to the shaft 3. and a.

` ST tending' to turn the shaft foraiid being' located ivitliin a barrel l to the huh of the gear 35 and to the barrel 35% so that the shaft 3 is normally under the tension of the spring' 3T. This sprii is ivealer than the spring; and the latte' serves to ret-cru all parts to their starting positions when the handle is released.

The segments 30 and 3i are arranged side by side, and the segment 230 is formed with the shoulder 39, li'ig. 20, on the rear side thereof, which engages the rear edge of the segment 34. fis the spring 3T tends to actu- `ate the shaft 3, the segment 34 is held against the shoulder 39. Hence, the shaft 8 is held from actuation by the shoulder 39 on the segment 50 which is under tension of the stronger spring 32. The segment is not keyed directly to the actuating shaft 1S but is connected to a disk 40 thereon by lost motion connection consisting of a shoulder 40a on said dish:l which presses against the segment 30 during the forward movement of the shaft 1S, and which is normally spaced apart from the segment. So far as this invention is concerned, the segment 3G may be considered as fixed to the shaft 1S. The shaft i8 is provided with a handle 4l, and when this handle is operated or pushed downwardly from its position shown in Fig. 3, the shaft 18 is rocked forwardly, and the segment 30 moved downwardly rotating the gear 3l and additionally Vtensioning the spring 32. During such movement of tl segment 30, the shoulder 39 thereon moves rearwardly gradually releasing the holding effect on the segment 34, and permitting the spring 8T to act, and to actuate the shaft 3 and the crank arm 6 which carriers the planetary pinion 4` and hence to actu-ate the recording wheel i in a forward direction. When the handle 4l is released the spring 32 which is stronger than the spring 23T returns the parts to their starting positions.

F rom the foregoing it will be seen that there are two sets of power transmitting parts between the main shaft 1S and the recording element l, one set operating to initially move the element in a forward direction, and the other operating to additionally move said element in a forward direction, and both sets operating to successively advance the elements l, 2. This actuating mechanism vfor the shaft 3, and the controlling mechanism to be described, and the operation thereof, are no part of this invention but constitute the subject matter of my pending application, Si'. No. 24672, filed pr. 29, i915, and the operating and controlling mechanisms are only of importance herein in order that the operation of the recording elements may be under-.

stood.

rilhe controlling mechanism comprises ieys or stops 42 mounted above the top plate 43 of the machine in two concentric circular rows or series, two pairs of controlling arms 44, and 46, 47 in the paths of which certain selected stops are kmovable downwardlyT below the Ytop plate, vertically eff-:tending shafts 48, 49, 50, 5l Figs. 3, 5, and 6, on the upper ends of which the controlling arms are mounted` and differential gearing between said shafts and the shaft 3. rlhe series of stops 42 are supported by a. movable carriage 52 Figs l and 5, which includes a perforated plate 53 through which the lower ends of the stops 42 extend, the stops being guided at their upper ends in a perforated plate 54 which is supported by posts rising from the top 48. rihe intermediate portions of these stops 42 are enlarged at 56 providing shoulders which rest on the plate 53 and which abut against the under side of the plate 54. The portions of the stops projecting through the plate 53, move when permitted, as hereinafter Ydescribed, through perforations in the top plate. 43 downwardly into the paths of the arms 44, 45, 46, 4'?. The carriage 52 moves downwardly by gravity, and is moved upwardly into its position shown in Fig. 5, by means of a lever arm 5 7 pivoted at 58 between its ends and having atrone end a fork 59 engaging an annular groove in the hub of the carriage 52, and having at its other end means for engaging a cam 60 on the shaft 1S which cam controls the movement of the carriage 52. The carriage 52 slides vertically on aV post 6l arising from the top plate 43.

T he stops 42 which are permitted to nieve into the paths of the controlling arms 44, 45, 46 and 4l', are determined by a card such as shown in Fig. 2S which has a circular series of graduations thereon. and numbers on the outer side of the graduations representing the hours of from 6 a. in. to l2 m. or the morning worlr hours, and numbers on the inner side of-tlie graduations running from l2 m. to 6 p. m.

The holes G2 are punched in the card opposite the graduations showing the time at which workman enters in the morning, leaves at noon, enters in the afternoon and leaves at night. These perforations are usually made by a time recorder for that purpose, but so far as this invention is con cerned, they may be made by hand.

rllhe perforated card is placed in the card slot or receiver 63 F ig. 2, located below the plate 43, and when the series of stops 42 are permitted to move downwardly by gravity upon the actuation of the shaft 18 as will be hereinafter described, the stops 42 that come into alinement with the holes in the perforated card in the receiver 63, pass through said holes into the paths of the controlling arms 44, 45, 46, and 47, and the remaining stops are limited in their movement by the card, the controlling arms passing over the graduations of the card representing the unelapsed time and the elapsed time spaces being untraversed by the controlling arms, hence the uiielapsed time is added and the wheel l turned to subtract the unelapsed time from the total capacity of the wheel l. to give they elapsed time. The differential gearing between the nested lll) shafts 48, 49, 50 and 51 include shaft sections 64, 65, Figs. 2, 6, and 8, differential gearing 66 connecting said shaft sections 64, 65 and branches between the shaft sections 64, 65 and each part of controlling arms 44, 45 or 46, 47, the branches including differential gearing.

The shaft sections 64 and 65 are sleeves rotatable on a vertical shaft 67 located near the nested shafts. The differential gearing 66 is provided with a bevel gear 68 which meshes with the bevel gear 69 on the shaft 3.

The opposing gears 70, 71 of the differential gear 66 between the shaft sections 64, and 65, in addition to meshing with the compensating pinions 72 are secured to flanges or disks 78, 74, Figs. 2, 6, 8, 9, and 10, which constitute the driving elements of the differential gearing 75, 76 in the branches. Said disk 78 carries the compensating pinions 77 of the branch differential gearing 7 5, and the disk 74 carries the compensating gears 78 for the branch differential gearing 74. The differential gearing in addition to the pinions 77 includes opposing gears 79, 8() carried by hollow shaft sections or hubs 81, 82 which are loosely mounted on the main shaft section 64. Said gears 79, mesh in the'ordinary manner with the compensating pinions 77 and are also connected to gea-rs 83, 84 mounted respectively on the` nested shafts 48, 49 on which the controlling arms 44, 45 are mounted. The gear 80 meshes directly7 with the gear 84 and the gear 79 meshes with an idler 85 which meshes with the gear 83. Hence, thevshafts 48, 49 are actuated in opposite directions.

The differential gearing 76 in addition to the compensating pinions 78 includes opposing gears 86, 87 carried by hollow shaft sections or hubs 88. 89 loosely mounted on the main shaft section 65. These gears 86, 87 mesh with the compensating pinions 78, and are also connected to'gears 90, 91 mounted respectively on the nested shafts 50, 51, the gear 86 meshing directly with the gear 9() and the gear 87 meshing with an idler 92 which meshes with the gea-r 91. Hence, the nested shaft sections 50, 51 and the controlling` arms 46, 47 rotate in opposite directions. The idlers 85, 92, Fig. are mounted on a sha-ft 98. In the operation of the controlling mechanism, the controlling arms 44, 45, 46, 47 start from a. common f starting point located in a position corresponding to the space between thc 6 a. m. and the 12 noon graduations on the card, and these arms separate varying distances as, for instance, is shown in Fig. 17.

TWhen the card is placed in the card receiver 63 and four of the stops 42 drop through four of the holes in the card into the paths of the controlling arms 44, 45, 46, 47 and the handle 41 is operated to rotate the shaft 3, the gear 69 on said shaft 3 rotates the gear 68 of the main differential 66, and all the shaft sections and all the different-ial gears rotate as a unit. As soon as one of the controlling arms 44, 45, 46, 47 engages a stop as for instance, the arm 45, it and it-s nested shaft 49, are held from rotation thus stopping the hollow hub or shaft section 82 and gear 8O of the differential gearing 75 from rotation so that the compensating pinions 77 of this differential gearing 7 5 will now be rotated on their own axes and all the other shaft sections will be rotated with increased speed carrying the arms 44, 46, 47 toward the three remaining stops. lVhenever another of the controlling arms engages a stop the remaining arms are actuated with still greater speed toward their stopping points, and whenever the third arm engages its stop, the fourth arm is actuated with still greater speed toward its destination, and when it engages its stop, the shaft 8 is held from rotation and the recording wheel 1, has set therein the total amount computed, that is, in the example, 84 hours elapsed time and 34 hours unelapsed.

The additional advance of the wheel 1, and the transferring operat-ion of any fractional part of a unit, by means of the mechanism including the parts 17, 15, 14, and 22, Figs. 11, to 18 now takes place. In the eX- ample illustrated on the card Fig. 28 on all four of the stop arms 44, 45, 46, 47 would come to rest at the same time, as the holes in the card are opposite each other.

The operation of this controlling mechanism is of no importance so far as this invention is concerned and it is only necessary to bear in mind that it controls the extent of movement of the recording wheel 1. For a full description of the operation of this controlling mechanism reference is had to my pending application referred to.

As seen in 17, the cam 17 is provided' with a shoult er 95 which moves into engagement'with the upper side of a hammer 96 having a hub loosely mounted on the shaft 18 and also having a platen head 97 for engaging and pressing the card in the card receiver against the type ofthe recording wheels at the printing line. A suitable inling ribbon 98 is interposed between the card and the type wheels. The ribbon winds off of one spool 99 onto another spool 99. rEhe printing mechanism is also described in my pending application referred to.

In operation, when the perforated card is placed in the card receiver and the handle 41 operated, the cam 60, Fig. 5, moves to the right permitting the stops 42 to move downwardly so that certain of them can move through the holes in the card into the paths of the controlling arms 44, 45, 46 and 47. During this part of 'the movement of Ving positions. 40

the shaft 18 the lost motion previously referred to'between the segment 30 and the disk l0 is taken up so that continued opera-V tion of the handle moves the segment 30 rearwardly carrying the shoulder 39 thereof away from the rear edge of the segment Y 34 so that said segment Beavis free to move rearwardly actuating the pinion' and theY shaft 3. rlhis movement of the segment 30 also additionally tensions the returning springBQ. The shafty vthrough the arm 6 Yand the planetary pinion 4c, actuates the recording wheel l, in a forward direction.

Y ItV also actuates the differential gearing of i l5 Vlever 15 thusV additionally actuating the wheel l and transferring any fractional part of a unit set in said wheel to the wheel 2 through the pinion il which now occupies a position similar to that shown in Fig. l2.

At this point the lever 14 has passed the rhighpoint orlift 25 of the camV 17 Vand arrives .at thef'outer concentric 1aortion of said cam, and during this part of the movement of the shaft 18 the hammer 96 is actu-r ated-to print the elapsed time on the card Vby reason of theshoulder 95, TEig. 17,*engaging the upperVV side of the hammer 96. r`llhe handle. l-l, is then released andV the spring 32 restores vthe parts to Atheir start- Although l have shown this machine` as adapted for 'computing units of time it may be used for Vvarious other computations, some of which are outlined in my pending application.
